brennan defended and strongly defended the use of drones but he distanced himself from how the bush administration questioned terror suspects. it looks like john brennan is gaining the support of several lawmakers after defending u.s. drone attacks on terror suspects, even americans. at least three have been killed so far. >> i think any american who did that should know well that they, in fact, are part of an enemy against us and that united states will do everything possible to destroy that enemy to save american lives. >> reporter: drones are used against imminent threats, he said, not as payback. but some are still concerned if it's legal and ask, what if the cia takes out the wrong person? >> we've got to see all, any and all, of those legal opinions, ones that the bipartisan group of senators asked for, before the vote. >> if you would remove that individual, please.
